1. Are they truely coordinate free or do they use an orthogonal coordinate system with symbolic expressions for the coordinate coefficients? 2. Can you use their packages from within a python program? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sympy" group.
